Seasonal dynamics of microbial communities, ammonia oxidizers and denitrifying bacteria in a wastewater treatment plant revealed by Illumina MiSeq sequencing and quantitative PCR

摘要

Activated sludge (AS) contains highly complex microbial communities,which is of significant importance of the pollutants removal in wastewater treatment plants (WWTPs).Especially,the ammonia oxidizers,including ammonia oxidizing archaea (AOA) and ammonia oxidizing bacteria(AOB),and denitrifying bacteria (DNB) are the key microorganisms for biological nitrogen removal from wastewater.
